i have my website with permalink,
till now everything was fine, but few days before i changed my permalink, now everything is going wrong,
now each and every page i am getting 404,
even my about-us and contact us pages, they are giving me 404 page
if i come to my site from google or any search engines, then also it gives me 404
i have 1000+ posts on my website, for each post & page from google i get 404 page, but within the website except pages i get no 404 page
my previous permalink:
%postname%/%category%/
now i added custom taxonomy to my permalink,
so now it is:%location%/%courses%/%postname%
I asked this question first also, but it was into wrong section i guess, thats why asking again and in detail.

http://wordpress.org/extend/plugins/custom-post-permalinks/ check this plugin, I’ve used it on a couple of sites and it works great.
I might be very wrong on this one, but I don’t think that you can add things like %location% or %courses% to your permalink structure. At least not out of nothing. So at least it looks like information about your configuration is missing to answer your question.
